Hello, this particular book may be the best one someone can get in order to have an organized and complete review. However, it should be noted that it is much more difficult than the others, and if someone manages to solve a large number of exercises from it, then all the other exercises from other resources, as well as from school, will seem trivial to them. As one of the top physics students, I struggled a lot in several parts, but the process of sitting down and solving the exercise, or even searching for similar and simpler exercises, is what ultimately helped me understand the concept of the exercise in a deeper way. I want to emphasize that this book indeed has crazy exercises and is not for the average 15-16 year old physics student who will give up in 10 minutes. Some exercises may take you half a day to solve on your own, but then you will never get stuck again. Also, although it is a physics book, it is only addressed to students in the science stream, as it requires derivatives, so if you are in the humanities stream, honestly don't bother, find an easier book for your level and get that one (in general, know that any book by Panagiotakopoulos is only for the science stream). In summary, this book is not for everyone, it is only for those who have dedicated themselves to physics in previous years and have a clear and systematic study. The exercises are more difficult than anything you have seen before, and in all the topics it covers, they are quite specialized. If you are one of those who have a passion for physics, I sincerely recommend it because, although you will struggle to solve all the exercises here and you will think you know nothing, as soon as you see exercises from other books (other resources or school), you will think they are really easy. Tip: the book has chapters on physics and deals with each one separately, but there are also combined exercises, for example in oscillations you will need to have also studied momentum. The book divides the exercises in each chapter into review exercises and deepening exercises. Having worked with this book a lot, I suggest you read and do the chapters in the order they are presented, and more specifically, do it like this: (1) read the theory of the chapter, from other books or resources (only in the part you want to review, not all at once) (2) Now go to the book you got and do several, but not all, of the review exercises from the chapter you just read. (3) Then do some, but not all, of the deepening exercises. It is also good to have a pencil and erase each exercise you have finished on the initial page where it lists which exercises to do, so that you don't get confused. (4) Do these 3 steps for each chapter, IN THE ORDER THEY ARE PRESENTED IN THE BOOK! And then, once you finish each chapter, you can start choosing random exercises that you haven't done or that you got stuck on before, and do them. I recommend choosing random topics from each chapter so that you can create a mini test.
